摘　　要：含酚废水对环境具有较大危害,去除废水中的酚含量对环境安全具有重要的意义。活性炭吸附和超声降解技术都被应用于废水处理中,本文首次将这2种技术联合起来处理含酚废水,并比较了活性炭吸附、超声降解和超声-活性炭联合技术3种方法的效果,表明超声—活性炭联合技术对苯酚的去除率高于单独使用活性炭吸附或超声降解,探讨了溶液pH值、超声时间、活性炭投加量等因素对联合处理含酚废水效果的影响,发现处理100 ml的0.01 mol/L,的模拟含酚废水,溶液pH值为5,超声处理20 mins,0.4 g活性炭振荡吸附20 mins,可使苯酚去除率达到83.9%。联合技术可以综合2种技术的优势,在废水处理中有着广阔的应用前景。The phenol wastewater is harmful to the environment.The removal of phenols is significant to the safety of environment.The method of activated carbon adsorption and the method of ultrasound degradation were used to deal with the wastewater.The united technologies of activated carbon and ultrasound was first introduced in the paper.The method of using activated carbon,using ultrasound technology or using ultrasound-activated carbon technology were compared.The experimental results indicated the removal exceeded of the phenol by using the united technologies was the highest.The ultrasound-activated carbon,the effects of pH,time,the amount of activated carbon were studied.The removal exceeded of phenol was 83.9%.When the effects ofpH was 5,the ultrasound time was 20 mins,the amount of activated carbon was 0.4 g,the time of oscillation was 20 mins.The united technologies has the advantages of both technologies integrated.It has broad application prospects.
